Founded in 1876, Texas A&M University is a U.S. public and comprehensive university offering a wide variety of academic programs far beyond its original label of agricultural and mechanical trainings. It is one of the few institutions holding triple federal designations as a land-, sea- and ...
A family of instruments developed by TRACOR to study the size and extent of populations of very small marine life by measuring the acoustic signals backscattered from them at frequencies in the MHz range. The TAPS sensors can be lowered through the water column in cast mode, attached to net systems such as the MOCNESS, or deployed on a SeaSoar unit.
Industry:Earth science
A field experiment of BALTEX. The objective of BASIS is to create and analyze an experimental data set for optimization and verification of coupled atmosphere– ice–ocean models. The specific objectives are:
investigation of water budget, momentum and thermal interaction at air–ice, air–sea and sea–ice boundaries;
investigation of the atmospheric boundary layer (ABL);
investigation of the ocean boundary layer (OBL); and
validation of coupled atmosphere–ice–ocean models. The intensive field phase of BASIS took place in the Gulf of Bothnia in the Baltic Sea in a boundary zone between the open sea and the ice–covered sea from February 16 to March 7, 1998. Ships used included the Swedish RV Argos and the Finnish RV Aranda.
Industry:Earth science
A field experiment taking place during February and March 1988 to gather data on two phenomena: air mass modification over the Loop Current, and return flow characteristics of modified polar air returning to the southern shores of the United States.
Industry:Earth science
A field investigation of the Kuroshio and the deep western boundary current east of Japan.
Industry:Earth science
A field study designed to determine physical mechanisms and processes, and their critical spatial and temporal combinations, which can account for the wintertime phenomenon of explosively developing over–ocean atmospheric storms. The field study took place from Dec. 1, 1988 to Feb. 1989.
Industry:Earth science
A fifty volume set of reports on the results of the Challenger Expedition. The six main sections of the report were narrative, physics and chemistry, deep–sea deposits, botany, zoology and a summary. A more detailed breakdown is:
Industry:Earth science
A fine-grained sediment of pelagic origin found on the deep-ocean floor. It contains more than 30% siliceous material of organic origin and is usually found below the carbon compensation depth at depths greater than 4500 m. Two types of this are radiolarian oozes and diatom oozes.
Industry:Earth science
A float with all of the capabilities of an ALACE float as well as a longer lifetime and a CTD profiler to obtain vertical temperature and salinity profiles.
Industry:Earth science
A fluid in which deformation is proportional to velocity gradients.
Industry:Earth science
A four-dimensional (latitude, longitude, depth, and time) digital model of temperature and salinity for the North and South Atlantic, the Pacific, the Indian Ocean north of 40° S, the Arctic Ocean, the Mediterranean Sea, and the Black Sea. It consists of coefficients of mathematical expressions describing vertical profiles of temperature and salnity on a half degree latitude-longitude grid for seasonal and annual time frames, with the actual profiles generated by combining the coefficients with the equations. Some regions are being updated to 10 minute resolution. Data for creating the GDEM were obtained from the Master Oceanographic Observational Data Set (MOODS) as well as from the Levitus climatology. It is used by the U.S. Navy for most of its operational systems.
